电感式磨粒传感器磨感电动势提取方法
|
摘要
利用高频交流电对三线圈电感式传感器进行激励,由于互感的作用,感应线圈产生的互感电动势对磨粒通过时产生的磨感电动势信号产生干扰。利用互感原理建立了传感器的数学模型,提出磨感电动势概念,并分析了磨感电动势的产生机理。利用锁相放大技术建立了磨感电动势的提取方法模型并进行仿真研究。通过设计试验提取出磨感电动势信号,验证了所建模型的正确性,为该传感器的设计提供了参考。
When a high-frequency alternating current is used to stimulate a three-coil inductive wear particle sensor when wear debris is passing by,a weak inductive electromotive force signal will be produced.Due to the effect of mutual inductance,the inductive coil produces a mutual inductive electromotive force,which brings in high levels of interference.An approach to eliminating this interference and extracting a high signal-to-noise ratio inductive electromotive force signal is of great significance in particle recognition,particle counting and fault estimation.The mathematical model of the sensor using the mutual inductance principle and the concept of wear inductive electromotive force is introduced.Then,the model of wear electromotive force extraction method is established based on the lock-in amplifier principle.Finally,the simulation and the experimental results validate the correctness of the model when the electromotive force signals are successfully separated,and provide the reference for the type of sensor design.
